Problems solved by technology

[0002] Construction vehicles such as piling machines and trucks have complex and diverse working environments. The body placed on the chassis is heavy. Due to factors such as uneven working ground or construction vibration, the chassis is easy to shake, and the wheels on the chassis will hang in the air, resulting in unstable walking. , uneven force, poor construction quality and other issues, if the shaking range makes multiple wheels suspended in the air, a rollover accident will occur, which will bring great safety hazards to vehicles and operators

Embodiment 1

[0027] Such as Figure 1 to Figure 7 , the frame chassis of the present embodiment comprises an underframe 1 welded by rectangular tubes, and left front wheels 2, right front wheels 3, left rear wheels 4 and right rear wheels 5 are respectively arranged on both sides of the underframe 1 , the front portion of the underframe 1 is provided with a crossbeam 11, the crossbeam 11 is hinged with a swing beam 7 with a U-shaped cross section through a pin shaft 8, and one end of the swing beam 7 is connected to the left front wheel 2 through a left support plate 26. Fixedly connected, the other end is fixedly connected with the right front wheel 3 through the right support plate 36 so that the underframe 1 can swing to ensure stability; the left rear wheel 4 and the right rear wheel 5 are driven by a hydraulic motor 9 respectively. In such a design, the 8 pins, the 4 left rear wheels and the 5 right rear wheels are equivalent to the three fulcrums of the chassis 1. On uneven ground, t...

Embodiment 2

[0035] The difference between this embodiment and the frame chassis of the above-mentioned embodiment 1 is that in the steering device of the front wheels of the frame chassis of this embodiment, the two front wheels are respectively equipped with a speed reducer to realize steering independently: the steering device includes a left cross shaft 22, Right cross shaft 32 and two speed reducers; the horizontal shaft of the left cross shaft 22 is sleeved on the left transmission shaft 21 of the left front wheel 2, and the vertical shaft is fixedly connected with the speed reducer fixed on the left support plate 26, so The horizontal shaft of the right cross shaft 32 is sleeved on the left drive shaft 31 of the right front wheel 3, and the vertical shaft is fixedly connected with the speed reducer fixed on the right support plate 36.

Abstract

The invention relates to a four-wheeled chassis for an engineering vehicle. The four-wheeled chassis for the engineering vehicle comprises a bottom frame formed by welding rectangular pipes. A left front wheel and a left rear wheel are arranged on one side of the bottom frame, and a right front wheel and a right rear wheel are arranged on the other side of the bottom frame. A cross beam is arranged on the front portion of the bottom frame. A swinging beam with the U-shaped section is hinged to the cross beam through a hinge pin. One end of the swinging beam is fixedly connected with the left front wheel through a left supporting plate, and the other end of the swinging beam is fixedly connected with the right front wheel through a right supporting plate so that the bottom frame can swing to ensure stability. The left rear wheel and the right rear wheel are driven by a hydraulic motor. The four-wheeled chassis for the engineering vehicle is simple in structure and can swing for adjustment so as to achieve stable traveling on the uneven ground.

technical field [0001] The invention relates to a four-wheel chassis for engineering vehicles. Background technique [0002] Construction vehicles such as piling machines and trucks have complex and diverse working environments. The body placed on the chassis is heavy. Due to factors such as uneven working ground or construction vibration, the chassis is easy to shake, and the wheels on the chassis will hang in the air, resulting in unstable walking. , uneven force, poor construction quality and other problems, if the shaking range makes multiple wheels suspended in the air, a rollover accident will occur, which will bring great safety hazards to vehicles and operators. Contents of the invention [0003] In order to solve the above problems, the present invention provides a four-wheel chassis for engineering vehicles, which has a simple structure and can be oscillatingly adjusted to achieve stable walking on uneven ground. [0004] The technical scheme that the present in...
