Abstract
Description
Technical Field
[0001] This utility model relates to the field of mini-truck technology, and in particular to a front suspension for a pure electric mini-truck. Background Technology
[0002] Traditional mini-trucks have a front suspension structure consisting of an integrated front axle and left and right leaf springs. When encountering poor road conditions, the vehicle body will sway from side to side, the chassis will be loose and make abnormal noises, and the bumps will be strong, resulting in poor driving comfort. Moreover, the steering is vague and the steering is not precise. In order to reduce costs, hydraulic power steering is often used instead of more precise electronic power steering. Combined with simple suspension geometry, this results in vague road feel from the steering wheel, a certain amount of play in the steering, and a "floating" steering at high speeds, lacking a sense of stability.
[0003] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0004] To address the aforementioned shortcomings, this utility model provides a front suspension for a pure electric mini-truck.
[0005] To achieve the above objectives, this utility model provides a front suspension for a pure electric mini-truck, comprising: a chassis, two sets of tires symmetrically arranged on the left and right sides of the chassis, each set of tires having a rim inside, each set of rims having a disc brake inside, a lower control arm between the chassis and the two sets of rims, a front damper on the lower control arm, a connecting arm on the top surface of the chassis, a frame on the top of the connecting arm, and the frame connected to the front damper; a front leaf spring assembly between the two sets of rims, a front leaf spring pressure block at the bottom of the frame, the front leaf spring assembly penetrating the interior of the front leaf spring pressure block, and positioning holes for connecting and positioning the front leaf spring assembly on the front leaf spring pressure block, the front leaf spring assembly, and the frame.
[0006] According to the present invention, a front suspension for a pure electric mini truck is provided at the bottom of the front leaf spring assembly, and a front brake upper ball joint is provided inside the front leaf spring ball joint, which is connected to the disc brake.
[0007] According to the present invention, a front suspension for a pure electric mini-truck is provided with a lower ball joint of a front brake connected to the top of the lower cross arm, and the lower ball joint of the front brake is connected to the disc brake.
[0008] According to the present invention, a front suspension for a pure electric mini-truck is provided on both the frame and the lower crossarm, and the top and bottom of the front damper are respectively connected to the hangers.
[0009] According to the present invention, the front suspension for a pure electric mini-truck is such that the lower control arm and the chassis, as well as the front damper and the lower control arm and the frame, are connected by buffer rubber sleeves.
[0010] This utility model provides a front suspension for a pure electric mini-truck, which adopts a centrally mounted transverse front leaf spring assembly for support. The front leaf spring assembly is securely connected to the front leaf spring pressure block at the bottom of the frame. At the same time, the subsequent connection through the positioning hole makes the front leaf spring assembly more centered and consistent. The two ends of the front leaf spring assembly are connected to the disc brake through the front leaf spring ball joint seat and the upper ball joint of the front brake, respectively. The lower part of the disc brake is connected to the lower control arm through the lower ball joint of the front brake. The lower control arm is connected to the frame through two buffer rubber sleeves, allowing the lower control arm to move along the axis of the buffer rubber sleeves. The two sets of disc brakes in this structure can move independently without being affected by the other side, and its comfort is comparable to that of a MacPherson independent suspension.

[0015] See Figures 1-3 This utility model provides a front suspension for a pure electric mini truck, comprising: a chassis 1, two sets of tires 2 symmetrically arranged on the left and right sides of the chassis 1, each set of tires 2 having a rim 3 inside, each set of rim 3 having a disc brake 7 inside, a lower crossarm 5 respectively between the chassis 1 and the two sets of rim 3, a front damper 8 provided on the lower crossarm 5, a connecting arm 6 provided on the top surface of the chassis 1, a frame 4 provided on the top of the connecting arm 6, and the frame 4 connected to the front damper 8; a front leaf spring assembly 9 provided between the two sets of rim 3, a front leaf spring pressure block 10 provided at the bottom of the frame 4, the front leaf spring assembly 9 penetrating the interior of the front leaf spring pressure block 10, and positioning holes 11 for connecting and positioning the front leaf spring assembly 9 provided on the front leaf spring pressure block 10, the front leaf spring assembly 9, and the frame 4.
[0016] See Figure 2 Preferably, the bottom of the front leaf spring assembly 9 of this utility model is provided with a front leaf spring ball joint seat 12, and the front leaf spring ball joint seat 12 is provided with a front brake upper ball joint 13. The front brake upper ball joint 13 is connected to the disc brake 7. The front leaf spring ball joint seat 12 facilitates connection with the front brake upper ball joint 13, thereby realizing the connection with the disc brake 7.
[0017] See Figure 2 In addition, the lower cross arm 5 of this utility model is connected to the top of the front brake lower ball joint 14, and the front brake lower ball joint 14 is connected to the disc brake 7.
