Take you to know the chassis knowledge of special purpose vehicle (two) skeleton car.

Through the previous understanding, we understand that the chassis plays a very important role in the performance of the special vehicle, a good choice of chassis can not only save themselves unnecessary costs, but also enhance driving experience, better reflect the special function of the special vehicle. In the face of many chassis manufacturers, how do we choose a suitable chassis?

In fact, the chassis of a special vehicle has a lot of parameters, and understanding these parameters can help us to determine the most appropriate chassis according to our own needs.

power

Anyone who understands the relationship between energy and work should know very well that to move an object, work must be done on it. Special purpose vehicle in the course of driving, need to constantly provide the driving force, the stronger the driving force, the more stable, the stronger the sports ability, the more prominent the acceleration capacity per unit time. Therefore, the power of the engine affects the speed of the car to a large extent.

Due to friction, loss of energy and other reasons, the power of the engine can not be fully reflected in the driving force of the vehicle, coupled with the impact of vehicle quality, the effective output power of the engine will be reduced. Therefore, we need to consider 75% - 90% load rate of the special vehicle to drive the special device work. According to this standard, we can know whether the engine is normal, full load or overloaded. This has great influence on the service life of the engine.

torqu

Torque, like power, also affects the mobility of vehicles, and their relationship with the engine is roughly as follows: under the same driving force, the faster the engine speed, the greater the power, the lower the torque; otherwise, the smaller the power, the greater the torque. Torque is more reflected in the energy that the engine crankshaft can turn around. It's very obvious from rest to motion or at low speeds. I think it's more appropriate to describe the torque of a vehicle with toughness.

For cars, the greater the torque, the better the acceleration effect of 0-100 km; for off-road vehicles, the greater the gradient; for trucks, the torque is reflected in the weight pulled. Generally, the weight of special purpose vehicles is much larger than that of cars, and the engine with larger torque can face all kinds of complex environment better. Heavy duty rollover trailer has high utilization rate.

Axis number

The choice of axle number is mainly related to the vehicle quality, the restriction of road regulations on axle load quality, the load capacity of tires and the structure of the vehicle. Generally speaking, the bearing weight of each axle should not exceed 9t.

At present, special cars can have two axes, three axes, four axes or even more axle numbers. Because of the simple structure and low manufacturing cost of the two-axle vehicle, the vehicle with the total mass less than 19T usually adopts this form.

Driving form

In the front, we understand the driving form, which is mainly reflected in the passing capacity of vehicles. It can well reflect the driving ability of vehicles on rough or soft soil and desert.

Minimum clearance, approach angle, departure angle, longitudinal passing angle, minimum turning diameter, internal wheel difference, turning passage circle and wheel radius are all important vehicle passing performance indicators. Many special vehicles work in a more complex environment, so they need strong driving capability. The capacity of skeleton cars is larger in trailers, and the number of users is larger.

Arrangement form

The engine layout and driving forms mainly include pre-drive, pre-drive, post-drive, middle-drive and all-wheel drive. In the special vehicle, the layout of the engine is more concerned with the convenience of modification.

Wheelbase

The wheelbase mainly affects the length, quality and performance of the special purpose vehicle. Under the premise of ensuring the function of the special purpose vehicle, the shorter the wheelbase, the better the maneuverability of the vehicle.

Wheelbase

Wheel spacing largely depends on the width of the vehicle, larger wheel spacing can increase the stability of the special device and increase the loading capacity, therefore, in line with the premise of total width, try to choose a chassis with wider wheel spacing.

Vehicle preparation qualit

For the special vehicle which needs to be refitted to complete the transportation task, the loading quality can be improved by choosing the special vehicle chassis with smaller complete quality.

For a special vehicle chassis, we need to know a lot of things, whether it is to buy a car or refitted car, car chassis applicability, reliability, convenience and price rationality are to be considered. Through the indicators, we can clearly understand the practicability of the product, and then combined with their own needs, to find the most suitable product for you.
