Description

Technical Field

[0001] This utility model relates to the field of commercial vehicle technology, and in particular to a lift pump bracket, a mudguard bracket, and a commercial vehicle. Background Technology

[0002] The main function of a commercial vehicle lift pump is to raise the cab to facilitate the maintenance of engine and other components located at the bottom of the cab. Lift pumps are typically installed using a lift bracket, which is mounted on the chassis adjacent to the mudguard bracket. Currently, there are two common installation methods for lift brackets:

[0003] (a) The mudguard bracket and the lifting bracket are separate structures. With the realization of chassis modularization, the layout space on the chassis is limited, making it impossible to achieve a distributed layout, and it is not conducive to the operation of the lifting pump.

[0004] (ii) The mudguard bracket and the lift bracket are an integrated structure. The existing lift bracket includes a tube beam and a mounting plate for mounting the lift pump, which is mounted on the tube beam. The mudguard bracket includes a support beam, a base located at one end of the support beam and connected to the commercial vehicle chassis, and a mounting bracket for mounting the mudguard on the support beam. The tube beam is fitted onto the support beam of the mudguard bracket, thus forming an integrated structure. Because the mounting plate is only fixed to the tube beam and has no other reinforcing structure, it cannot withstand the load when the lift pump is working, resulting in severe low-frequency shaking.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0027] like Figure 1 , Figure 2 As shown, the lifting pump bracket 1 provided in this embodiment includes a pipe beam 11, a mounting plate 12, a side plate 13, and a support plate 14.

[0028] The tube beam 11 is a steel pipe that extends through both ends, and has an internal mounting cavity 111 for fitting onto the support beam 3. The tube beam 11 has a length L.

[0029] Both the mounting plate 12 and the side plate 13 have sleeve holes at their upper ends that can be fitted onto the pipe beam 11. After the mounting plate 12 and the side plate 13 are fitted onto the pipe beam 11 through their respective sleeve holes, they are vertically connected to the pipe beam 11 to solve the problem of the rigidity of the lifting pump bracket. The mounting plate 12 has mounting holes for connecting to the lifting pump. Both the mounting plate 12 and the side plate 13 have vertical and horizontal sides, and a right chamfer 121 is provided between the vertical and horizontal sides of the mounting plate 12.

[0030] The support plate 14 includes a first plate 141 and a second plate 142 that are bent and connected together. The first plate 141 is provided with two slots 144, one of which is inserted into the vertical side of the side plate 13, and the other slot 144 is inserted into the vertical side of the mounting plate 12. After insertion, the right angle formed at the joint is easy to weld.

[0031] The second plate 142 is connected to both the side plate 13 and the mounting plate 12 on the side away from the pipe beam 11. The straight chamfer 121 is located at the corner of the first plate 141 and the second plate 142. The outer periphery of the second plate 142 is provided with a rounded chamfer 143.

[0032] The pipe beam 11 has a length L, the support plate 14 has a width W1, and the side plate 13 and the mounting plate 12 have a gap W2, where W2 < W1 < L. This structural design facilitates welding and solves the problem of weak weld strength between the pipe beam and the mounting plate.

[0033] like Figure 3 As shown, this utility model also provides a mudguard bracket, including a support beam 3, a base 2, a mounting bracket 4, and the aforementioned lift pump bracket 1.

Two mounting brackets 4 are spaced apart, and the lift pump bracket is located between the two mounting brackets 4. The pipe beam 11 of the lift pump bracket 1 is fitted onto the support beam 3 through the mounting cavity 111. The mounting plate 12 on the lift pump bracket 1 is disposed away from the base 2. The support beam 3 is a bent pipe.

[0034] This utility model also provides a commercial vehicle, including a chassis, a cab, mudguards, a lift pump, and the aforementioned mudguard bracket. The chassis includes a frame. The base 2 on the mudguard bracket is mounted on the frame, the mudguard is mounted on a mounting bracket 4, and the lift pump is mounted on a mounting plate 12.
