Description

Automobile with hydraulic shifting device

Technical Field

The utility model relates to a commercial car chassis and whole car production field especially relate to a hydraulic pressure shift unit's car.

Background

With the economic development and the improvement of road conditions, the performance requirements of the commercial vehicles are higher and higher by customers. Stable power performance, good fuel economy, comfortable driving experience, and efficient transportation efficiency are increasingly being of interest to users. Especially the high transportation efficiency, directly affects the income of users. Aiming at the change of the user requirements, the technical improvement is continuously carried out in the field of commercial vehicles, and the user requirements are met.

Along with the improvement of the requirement of customers on the transportation efficiency, the opening modes of the container side boards on the market are increased day by day, the single rear opening door is increased to the rear opening door plus the side opening door, and the requirement of customers on three-opening doors, five-opening doors and even seven-opening doors is increased day by day when the customers select the containers. The dumper mainly transports sand and stone materials, crops, coal and soil and building materials, most of the cargoes are free-running, and after the cargoes are unloaded, the problem that the tires of the vehicles skid and cannot run due to the fact that the wheels of rear axles are buried by the free-running cargoes is often caused. On the other hand, on rural and national road surfaces in some underdeveloped areas in China, cargo vehicles with long wheelbases and large rear overhang sizes can get stuck due to the fact that the turning radius of the vehicles is too large when passing through a sharp-bend road section, drivers need to adjust the advancing and retreating and steering of the vehicles back and forth to get rid of difficulties and pass, the running efficiency of the road vehicles is seriously affected, and large potential safety hazards exist.

At present, the problem that the tires of the rear axle of the vehicle are buried by the free-running goods is solved, and the running efficiency of the vehicle is improved. Most users use tools that either manually dig out the cargo or ask another vehicle to assist in pushing the cargo box. Some commercial vehicle manufacturers in the market control the quantity of fluid cargos entering a vehicle chassis by limiting the overturning angle of a cargo box and the opening mode of a sideboard (an overturning shaft is arranged at a lower supporting plate of the cargo box), however, the overturning angle of the cargo box is limited too much, so that cargo residues are often generated, and the manual workload needs to be increased; on the other hand, the opening process of the container side plate in a single container opening mode (upward opening) is high in speed and large in stroke, and the container side plate and the tail plate are easy to collide with other parts of the chassis to impact when fluid goods are unloaded, so that the container side plate is damaged, and personal injury is easy to occur to users.

In order to avoid the vehicle jam fault caused by the overlarge turning radius of the long-wheelbase vehicle, most truck drivers have to change the driving route to bypass a special route or change the driving to the highway, and the driving mileage and the transportation cost are increased. Other truck drivers may add a passenger to direct operations on a particular road segment. These not only increase vehicle transportation cost, reduce vehicle transportation efficiency, also have higher road operation safety risk. In addition, vehicles running in forest areas and construction sites are greatly limited by the environment, wheel skidding is easy to occur when the vehicles run on rainy and wet roads, and the vehicles cannot run, most users can only change large pattern tires to increase the friction force with the ground, however, the fuel consumption is directly increased greatly after the tires are changed, the tires are easy to wear, and the fuel economy and the transportation cost of the vehicles are not facilitated; other users who do not need to select large-pattern tires can only get rid of difficulties by traction of other vehicles, and have the problems of more personnel, complex equipment, high cost, low efficiency and the like.
