Embodiment 1

[0073] see figure 1 — Figure 17 , a multi-suspension external connection system on an electric vehicle, comprising a vehicle frame 8 and a suspension connection device connected thereto, the vehicle frame 8 comprising a rear beam 83 and a left longitudinal beam 81 connected to its two ends, Right longitudinal beam 82; the tail end of the left longitudinal beam 81 is connected with the tail end of the right longitudinal beam 82 through the rear cross beam 83, and the middle part of the left longitudinal beam 81 is connected with the middle part of the right longitudinal beam 82 through the No. 1 cross beam 84, The middle part of No. 1 crossbeam 84 is connected with the middle part of back crossbeam 83 by short longitudinal beam 87, and the middle part of short longitudinal beam 87 is vertically connected with the middle part of No. 2 crossbeam 85, No. 3 crossbeam 86 respectively, and the two ends of No. 2 crossbeam 85 are connected with The middle parts of the left longitudin...

Embodiment 2

[0075] Basic content is the same as embodiment 1, the difference is:

[0076] The structure of the left shock absorbing module 20, the right shock absorbing module 40, and the rear shock absorbing module 60 are consistent, and all include a vulcanized sleeve 601, rubber 602, inner shell 603 and outer shell 604; the outer shell of the sleeve 601 Wrapped with rubber 602, the outside of the rubber 602 is wrapped with an inner shell 603, the outside of the inner shell 603 is wrapped with an outer shell 604, and an upper shock-absorbing cavity 605 and a lower shock-absorbing cavity 606 are opened in the rubber 602; The tube passing shafts 9 in the left connection unit 3 , the right connection unit 5 , and the rear connection unit 7 all pass through the corresponding single casing 601 . The central axes of the inner sleeves 601 of the left suspension 2 and the right suspension 4 are parallel to each other, and the central axes of the inner sleeves 601 of the left suspension 2 and th...

Embodiment 3

[0078] Basic content is the same as embodiment 1, the difference is:

[0079] See Figure 17 , this figure is the pointed bolt 10 used when the present invention carries out the bolted connection, and it is also used as the pipe-through shaft 9 simultaneously. The pointed bolt 10 comprises a nut 101, a screw section 102, a threaded section 103, and a bolt head 104 connected in sequence, and the side wall of the threaded section 103 is provided with external threads, and the top of the bolt head 104 is connected to the threaded section. 103, the bottom end of the bolt head 104 extends outwards, and the diameter of the bolt head 104 is tapered from top to bottom.

Abstract

The invention discloses a multi-suspension external connection system on an electric automobile, which comprises a frame and a suspension connecting device, wherein the frame comprises a rear cross beam, a left longitudinal beam, a right longitudinal beam, a short longitudinal beam and three cross beams which are connected with one another; the suspension connecting device comprises a left connecting unit, a right connecting unit and a rear connecting unit; the part, which is clamped between the first cross beam and the second cross beam, of the short longitudinal beam is connected with the top end of the left connecting unit; the part, which is clamped between the first cross beam and the second cross beam, of the right longitudinal beam is connected with the top end of the right connecting unit; the part, which is clamped between the right longitudinal beam and the short longitudinal beam, of the third cross beam is connected with the top end of the rear connecting unit; and the bottom ends of the left connecting unit, the right connecting unit and the rear connecting unit are each provided with a pipe penetrating shaft to be connected with corresponding damping modules on left,middle and rear suspensions. According to the design, the assembling difficulty is low, the assembling efficiency is high, the manufacturing cost is low, and the vibration reduction effect is good.

Description

technical field [0001] The invention relates to a connection layout design of a suspension on a vehicle frame, belongs to the field of pure electric vehicles and components of the pure electric vehicle, and in particular relates to an external connection system of multiple suspensions on an electric vehicle. Background technique [0002] According to the needs of the drive form, the layout of the powertrain is often arranged in the front cabin and the cockpit, and these two layouts have the form of front-mounted front-drive and rear-mounted rear-drive respectively. For the front-wheel drive, the suspension layout space, structural requirements and installation process requirements of the powertrain are not high, and it is easy to realize, but the rear-mounted rear drive, that is, when the powertrain is arranged at the rear axle of the vehicle, especially pure For electric van transport vehicles, the powertrain is completely under the floor, and the installation space is limi...
