Description

A kind of driving cab rear suspension with stopper

Technical field

The present invention relates to a kind of auto parts and components, and in particular to a kind of driving cab rear suspension with stopper.

Background technology

At present, the driving cab rear suspension of light, middle truck, is typically all fixed by bracket assembly, rear support cushion and vehicle body Support is constituted.Bracket assembly is coupled by locking bolt fastening with rear support cushion, and rear support cushion is led to vehicle body fixed support Cross bolt everywhere to connect firmly, connect driver's cabin on bracket assembly, under vehicle body fixed support, connect frame beam.Rear support cushion is used as driving Flexible member in the rear-suspending of room, in vehicle travel process, after the vibration of the vehicle such as road shocks and engine itself passes through The caoutchouc elasticity of support cushion deforms to buffer.But when vehicle is travelled in severe road conditions, after driver's cabin bob has exceeded The rubber tensile strength degree of support cushion, will cause the tear of rear support cushion rubber or deviate from, so that driving cab rear suspension Failure, increased the replacement cost of driving cab rear suspension, causes to waste.

Content of the invention

It is an object of the invention to provide a kind of driving cab rear suspension with stopper.

For achieving the above object, the technical solution used in the present invention is：A kind of driving cab rear suspension with stopper, bag Bracket assembly, vehicle body fixed mount and buffer system is included, the bracket assembly includes vertical plate and flat U-board, the vertical plate Head is provided with pilot hole, and the lower center position of the flat U-board is provided with mounting groove, and the upper end of the vehicle body fixed mount is provided with U Shape groove, is provided with buffer system between the mounting groove and U-lag；

The buffer system includes lock ring bolt, upper limit position block, rear support cushion, lower position block and slotted nut, the lock ring Bolt tail be located at vertical plate bottom, its head through flat U-board reach U-lag in, the lock ring bolt from bottom to the end Portion is sequentially provided with upper limit position block, rear support cushion, lower position block and slotted nut, and the upper limit position block is located at the bottom of mounting groove Portion, cooperation of the rear support cushion by hexagon-headed bolt with hex nut are arranged on the installing hole at the top of vehicle body fixed mount Interior, head of the slotted nut installed in lock ring bolt, the lower position block are located at the top against slotted nut, described on Limited block and lower position block leave equidistant space with support cushion.

As a result of above-mentioned technical proposal, the invention has the advantages that：The present invention is jumped up and down according to driver's cabin In dynamic scope and rear support cushion, the tensile strength of rubber to be arranging the gap of upper and lower limited block and rear support cushion, using upper, The contact of lower position block is spacing protecting rear support cushion, makes the rubber tensile of rear support cushion be in rubber tensile intensity all the time Within limit range, so as to the rubber of effective protection rear support cushion is unlikely to tear or deviates from, driving cab rear suspension is reduced Frequent failure replacement cost, saves user's use and maintenance cost, improves the satisfaction of user.

Specific embodiment

As illustrated in fig. 1 and 2, the technical solution used in the present invention is：A kind of driving cab rear suspension with stopper, including Bracket assembly 1, vehicle body fixed mount 2 and buffer system 3, the bracket assembly 1 include vertical plate 4 and flat U-board 5, described vertical The head of plate 4 is provided with pilot hole 6, and the lower center position of the flat U-board 5 is provided with mounting groove 7, the vehicle body fixed mount 2 Upper end is provided with U-lag 8, is provided with buffer system 3 between the mounting groove 7 and U-lag 8；

The buffer system 3 includes lock ring bolt 9, upper limit position block 10, rear support cushion 11, lower position block 12 and slotted nut 13,9 afterbody of lock ring bolt is located at the bottom of vertical plate 4, and its head is reached in U-lag 8 through flat U-board 5, the lock ring Bolt 9 is sequentially provided with upper limit position block 10, rear support cushion 11, lower position block 12 and slotted nut 13 from bottom to head, described Upper limit position block 10 is located at the bottom of mounting groove 7, and the rear support cushion 11 is matched somebody with somebody by hexagon-headed bolt 14 and hex nut 15 Close in the installing hole at the top of the vehicle body fixed mount 2, head of the slotted nut 13 installed in lock ring bolt 9, described under Limited block 12 is located at against the top of slotted nut 13, the upper limit position block 10 and lower position block 12 and support cushion 11 leave away from From equal space.

By arrangement above, the operation principle of the present invention is as follows：Bracket assembly 1 is connected with driver's cabin upwards, and vehicle body is fixed Support 2 is connected with frame beam downwards.When driver's cabin bob, the rubber tensile stroke of rear support cushion 11 is made in rubber In the range of tensile breaking point is allowed.When jumping under driver's cabin, upper limit position block 10 contacts limit with above rear support cushion 11 Position；When on driver's cabin jump when, lower position block 12 with contact below rear support cushion 11 spacing, it is ensured that the rubber of rear support cushion 11 Within the scope of glue stretching is in rubber tensile strength degree all the time, so as to the rubber of effective protection rear support cushion 11 is unlikely to tear Split or deviate from, reduce driving cab rear suspension frequent failure replacement cost, save user's use and maintenance cost, improve user Satisfaction.

Above content is detailed description made for the present invention with reference to specific preferred embodiment, it is impossible to assert the present invention Specific embodiment be confined to these explanations.For general technical staff of the technical field of the invention, not On the premise of departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention and be carried The scope of patent protection that claims of friendship determine.
