Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of an orientation word such as "width direction" refers to a direction perpendicular to the length of the vehicle, unless otherwise specified.

Referring to fig. 1 to 4, an embodiment of the present disclosure provides a front and rear suspension disassembly and assembly assisting device including a tray 100, two first supports 120 for supporting a front suspension cross member or a rear suspension cross member, and two second supports for supporting a rear suspension shock-absorbing spring bracket.

The two first supporting pieces 120 are arranged on the tray 100 at intervals along the width direction of the automobile and are provided with clamping portions for clamping the front suspension cross beam or the rear suspension cross beam, the two second supporting pieces are arranged on the tray 100 at intervals along the width direction of the automobile and are provided with supporting portions 133 for supporting the rear suspension damping spring support, and the distance between the two supporting portions 133 is adjustable, wherein the tray 100 can be arranged into a plate-shaped structure so as to install the first supporting pieces 120 and the second supporting pieces, and the connecting line of the mounting points of the two first supporting pieces 120 on the tray 100 and the connecting line of the mounting points of the two second supporting pieces on the tray 100 form a trapezoid or a rectangle, namely, the connecting line of the mounting points of the two first supporting pieces 120 on the tray 100 can be a rectangle or a trapezoid.

With the above technical solution, the auxiliary device for front and rear suspension assembly and disassembly in this embodiment can use the two first supporting members 120 to support the front suspension beam or the rear suspension beam, when the front suspension is disassembled, since the front suspension cross beam has a wider cross neck, the front suspension cross beam can be fixed by the clamping portion of the first support member 120, when the rear suspension is disassembled, considering that the transverse neck of the rear suspension cross beam is smaller than that of the front suspension, therefore, the two second supporting pieces are arranged to support the rear suspension damping spring support, and the supporting mode is not only suitable for stably supporting the front suspension, but also suitable for stably supporting the rear suspension, make the dismantlement operation of front overhang and back overhang no longer supported by the staff, both reduced staff's human cost and operation intensity, avoided personnel extravagant, also avoided the staff to receive the injury when the operation simultaneously, guaranteed the security of operation. In addition, because the distance between two supporting parts 133 is adjustable, namely, the distance between two supporting parts 133 can increase or reduce, can make front and back hang dismouting auxiliary device can be applicable to the rear overhang of different size like this to make front and back hang dismouting auxiliary device can be applicable to different motorcycle types, improved front and back hang dismouting auxiliary device's application scope.

Referring to fig. 1 and 2, further, the second support includes a support arm 131 and a telescopic arm 132, the support arm 131 is mounted on the tray 100, the support arm 131 can be fixed on the tray 100 by a fastener 134, the fastener 134 can be a bolt, the support arm 131 extends outward of the tray 100, one end of the telescopic arm 132 is slidably connected to the support arm 131, the support portion 133 is disposed at the other end of the telescopic arm 132 and extends in a direction away from the surface of the tray 100, since the telescopic arm 132 can slide relative to the support arm 131, the length of the telescopic arm 132 and the support arm 131 in the width direction of the vehicle can be changed, and moreover, by means of the sliding connection, the connection structure of the telescopic arm 132 and the support arm 131 can be simplified.

It can be understood that, when the line of the four mounting points of the first and

second supports

120 and 120 is rectangular, in order to enable the support portion 133 on the telescopic arm 132 to support the rear suspension shock-absorbing spring bracket, the length of the whole of the telescopic arm 132 and the support arm 131 is long, and when the line of the four mounting points is trapezoidal, and the mounting point of the second support is close to the width direction of the tray 100 with respect to the mounting point of the first support 120, the length of the whole of the telescopic arm 132 and the support arm 131 can be reduced, that is, when the line of the mounting points of the two second supports is greater than the line of the mounting points of the two first supports 120, the length of the telescopic arm 132 and the support arm 131 can be shortened, thereby saving the manufacturing material.

Referring to fig. 1 and 2, the second support member further includes a second fixing member 1313, the support arm 131 and the telescopic arm 132 are respectively provided with a second sliding slot 1312 corresponding to each other, that is, the second sliding slot 1312 on the support arm 131 and the second sliding slot 1312 on the telescopic arm 132 may be overlapped with each other, or after the telescopic arm 132 is away from the support arm 131, the second sliding slot 1312 on the support arm 131 and the second sliding slot 1312 on the telescopic arm 132 are staggered with each other, and the second fixing member 1313 respectively passes through the second sliding slot 1312 on the support arm 131 and the second sliding slot 1312 on the telescopic arm 132 to lock or release the telescopic arm 132 to the support arm 131.

Wherein, the second fixing member 1313 may be provided as a bolt and a nut, so that after the telescopic arm 132 moves, the second fixing member 1313 passes through the second sliding groove 1312 of the support arm 131 and the second sliding groove 1312 of the telescopic arm 132 to be locked to the support arm 131 by the telescopic arm 132, thereby ensuring the stability of the connection between the support arm 131 and the telescopic arm 132, and ensuring the stable support of the rear suspension damping spring bracket during the disassembling and assembling work.

It can be understood that when the overall length of the telescopic arm 132 and the support arm 131 needs to be adjusted, the nut is firstly unscrewed, the telescopic arm 132 is pulled, and after the telescopic arm 132 reaches a predetermined position, the nut is sleeved on the bolt to be locked, so that the telescopic arm 132 can be locked relative to the support arm 131, and the connection stability of the telescopic arm 132 and the support arm 131 is ensured.
