H-type power chassis with function of adjusting ground clearance and wheel tread

Abstract

The invention discloses an H-type power chassis with a function of adjusting a ground clearance and a wheel tread. The H-type power chassis comprises a chassis, and an engine, a clutch, a gear box, a differential mechanism, transfer cases, chain wheel transmission mechanisms and wheels which are arranged on the chassis, wherein power of the engine passes through the gear box to reach the differential mechanism, and then passes through the transfer cases on the two sides of the chassis to be transferred to the chain wheel transmission mechanisms on two sides through a left output shaft and a right output shaft of the differential mechanism, so that the power is transferred to the wheels which are connected with the chain wheel transmission mechanisms on two sides. The H-type power chassis has the advantages that: the front and rear wheels on the side have the same transmission ratio; when only one of the wheels on the same side slips and the other wheel does not slip, torque can be transferred to the wheel which does not slip, and driving power is generated by using adhesion of the wheel which does not slip, so that an automobile can start smoothly or runs continuously, and the pass-through performance of the automobile under the condition of a rugged road surface is improved. The ground clearance of the chassis and the wheel tread can be adjusted, and the H-type power chassis adapts to running of the rugged road surfaces of mountains, hills and the like, and has high pass-through performance, riding comfort, and stability.

Description

technical field [0001] The invention relates to a power chassis, which belongs to the field of vehicle engineering, in particular to an H-shaped power chassis with the function of adjusting ground clearance and wheelbase. Background technique [0002] Existing automobile chassis usually consists of engine, clutch, gearbox, differential, and wheels. Among them, the power of the transmitter is transmitted to the differential through the clutch, gearbox, and drive shaft, and the differential distributes the power to The left and right half shafts drive the left and right wheels. [0003] Among them, when the differential is installed between the two front wheels of the car and distributes the power to the two front wheels of the car through the left and right axle shafts, it is called front-wheel drive. When the differential is installed between the two rear wheels of the car and distributes the power to the two rear wheels of the car through the left and right axle shafts, it...

AI Technical Summary

Problems solved by technology

Its disadvantages are: because the front wheels are responsible for steering and driving at the same time, the high-speed stability is poor, the driving wheel is easy to slip when going uphill, and it is easy to overturn when going downhill at high speed

The disadvantages of this type of drive are: the heavy load on the rear axle makes the car have a tendency to over-steer, the adhesion of the front wheels is small, the steering is unstable at high speeds, and the assembly and manufacturing costs are higher compared to front-wheel drive, and more faults, relatively small indoor space, etc.

However, the structure of all-wheel drive is complicated, the cost is high, the fuel consumption is large when driving on a good road, and the wear and tear of tires and parts is large.

[0007] For the above three driving modes, when one side of the wheel slips, due to the existence of the differential, the slipping wheel turns faster and faster, and the other side turns slower and slower, causing the drive axle to lose its driving force, resulting in the vehicle being unable to drive
