Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorber brackets, in particular to a lower bracket of a shock absorber for a new energy light truck. Background Art

[0002] Shock absorbers are devices used to dampen the rebound oscillations caused by springs after absorbing shock, as well as impacts from the road. They are widely used in automobiles to improve ride smoothness. Their primary function is to accelerate the attenuation of frame and body vibrations, thereby improving ride comfort and handling.

[0003] Shock absorbers primarily operate through hydraulic forces. When the vehicle frame (or body) and axle vibrate and move relative to each other, the piston inside the shock absorber moves up and down. The oil in the shock absorber cavity repeatedly flows through micropores into the piston, generating a damping force that suppresses the reciprocating motion of the spring. This damping force can be adjusted based on different driving modes and road conditions to improve driving safety and comfort.

[0004] Light trucks are N2 trucks with a maximum gross design mass of no more than 4.5 tons, a subcategory of trucks. The high-end light truck market has seen rapid growth in recent years, paving the way for the emergence of new energy light trucks.

[0005] Currently, most new energy light trucks achieve lightweight design through electric drive axle drive systems. However, as motor power continues to increase, motor size also increases. When the brake chamber and motor are arranged on the same side of the axle, there will be serious interference between the brake chamber and the motor arrangement. When the motor is arranged on one side of the axle and the brake chamber on the other side of the axle, there will be interference between the traditional shock absorber lower bracket and the brake adjustment arm, which cannot meet actual installation requirements. Utility Model Content

[0007] The utility model is realized through the following technical solutions:

[0008] A lower bracket of a shock absorber for a new energy light truck includes a base that can be installed in a fit with the lower side of an axle support seat, and the base is provided with two mounting holes that can be connected and installed with suspension riding bolts; a transition connecting arm is connected to the inner side of the base, and a kingpin that can be installed with a support through the shock absorber is connected to the inner side of the transition connecting arm, and a clearance space is formed on the front side of the transition connecting arm to avoid the travel of the brake adjustment arm.

[0009] A further improvement of the present invention is that two mounting holes are provided correspondingly inside and outside.

[0010] A further improvement of the present invention is that mounting bosses are respectively provided at the upper and lower ends of the mounting hole.

[0011] A further improvement of the present invention is that the mounting boss of the outer mounting hole is circular, and the mounting boss of the inner mounting hole is in the shape of an elongated strip extending backward.

[0012] A further improvement of the present invention is that a screw is provided at one end of the kingpin away from the transition connecting arm, and the screw is used for screwing and mounting a shock absorber nut at the lower end of the shock absorber.

[0013] A further improvement of the present invention is that an end of the screw away from the kingpin is provided with a chamfer.

[0014] A further improvement of the present invention is that the distance between the kingpin axis and the upper mounting boss surface is S.

[0015] A further improvement of the present invention is that the kingpin axis is located in front of the line connecting the two mounting holes.

[0016] A further improvement of the present invention is that a stepped platform is provided at one end of the kingpin close to the transition connecting arm, and the stepped platform is used to locate the mounting hole at the lower end of the shock absorber.

[0017] A further improvement of the present invention is that the lower bracket of the shock absorber is integrally cast.

[0018] It can be seen from the above technical solutions that the beneficial effects of the present invention are:

[0019] During installation, the suspension riding bolt passes through the two mounting holes from top to bottom, and the riding bolt nut is screwed on the bottom of the suspension riding bolt, so that the upper side of the base is fitted and pressed against the axle support seat, thereby achieving reliable fixed installation of the entire bracket; the kingpin passes through the pin hole at the lower end of the shock absorber, thereby achieving support for the lower end of the shock absorber; and a avoidance space is provided on the front side of the transition connecting arm, through which the brake adjustment arm can be avoided in the braking state, effectively avoiding interference between the bracket and the brake adjustment arm, ensuring the swing space of the brake adjustment arm, and providing the prerequisite for the installation of high-power electric drive axles.

[0028] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0029] like Figure 1-6 As shown, the utility model discloses a lower bracket of a shock absorber for a new energy light truck, comprising a base 5 that can be fitted with the lower side of a vehicle axle support seat, and the base 5 is provided with two vertical mounting holes 6 that can be connected and installed with suspension riding bolts; a transition connecting arm 4 is connected to the inner side of the base 5, and a kingpin 2 in the inner and outer directions that can be installed with the shock absorber through-support is connected to the inner side of the transition connecting arm 4, and a avoidance space is formed on the front side of the transition connecting arm 4 to avoid the travel of the brake adjustment arm.

[0030] During installation, the suspension riding bolt passes through the two mounting holes 6 from top to bottom, and the riding bolt nut 9 is screwed on the bottom of the suspension riding bolt to make the upper side of the base 5 fit tightly with the axle support seat to achieve reliable fixed installation of the entire bracket; the kingpin 2 passes through the pin hole at the lower end of the shock absorber to support the lower end of the shock absorber; and a clearance space is provided on the front side of the transition connecting arm 4, such as Figure 5As shown, A1 is the brake adjusting arm in the non-braking state, and A2 is the brake adjusting arm in the braking state. The avoidance space is used to avoid the brake adjusting arm in the braking state, effectively avoiding interference between the bracket and the brake adjusting arm, ensuring the swing space of the brake adjusting arm, and providing the prerequisite for the installation of high-power electric drive axles.

[0031] This new energy light truck shock absorber lower bracket is suitable for installation on high-power electric drive axles. The motor is arranged on one side of the axle and the brake chamber is arranged on the other side of the axle.

[0032] The transition connecting arm 4 is an L-shaped bending structure as a whole, thereby forming a space for avoiding the travel of the brake adjustment arm.

[0033] Furthermore, two mounting holes 6 are provided correspondingly inside and outside, and the overall structure is simple, compact, and easy to form. Mounting bosses 7 are provided at the upper and lower ends of the mounting hole 6, respectively. The mounting bosses 7 are machined and formed, which is easy to implement and ensures the overall installation accuracy.

[0034] Among them, such as Figure 2 As shown, the mounting boss 7 of the outer mounting hole 6 is circular, and the mounting boss 7 of the inner mounting hole 6 is in the shape of a long strip extending backward, thereby ensuring the stability of the press fit with the lower side of the axle support seat.

[0035] The inner section of the kingpin 2 is provided with a screw 1, which is used to screw onto the shock absorber nut 8 at the lower end of the shock absorber. After the kingpin 2 passes through the hole at the lower end of the shock absorber, the shock absorber nut 8 is screwed onto the screw 1, achieving reliable and convenient installation of the shock absorber.

[0036] Among them, the end of the screw rod 1 away from the main pin 2 is provided with a chamfer, which plays a guiding role and facilitates the installation of the shock absorber nut 8.

[0037] like Figure 3 As shown, the distance between the axis of the kingpin 2 and the surface of the upper mounting boss 7 is S, that is, the kingpin 2 has a certain height difference relative to the base 5, S is greater than twice the thickness of the base 5, and the kingpin 2 is set low to effectively avoid interference with the axle housing.

[0038] like Figure 2 As shown, the axis of the kingpin 2 is located in front of the line connecting the two mounting holes 6. This ensures the swing space of the brake adjustment arm and the stroke of the shock absorber.

[0039] The outer end of the kingpin 2 is provided with a stepped platform 3, which is used to locate the mounting hole at the lower end of the shock absorber, ensuring the installation positioning and reliability of the shock absorber.
