Abstract
The utility model discloses a back suspension device of a cab, which comprises the following components: an upper bracket, a hydraulic lock, a spring damper assembly, a transverse damper and a lower bracket. According to the back suspension device of the cab, the vibration which is transmitted from a vehicle bracket to the cab in the vertical direction is reduced through the spring damper assembly, and the transverse swinging and vibration of the cab are reduced through the transverse damper. Through reasonably arranging the back suspension, a back suspension function is realized. The back suspension device of the cab has the following functions: small occupation space and space utilization rate increase.
Description
Technical field
The utility model relates to a kind of truck auxiliary device, is specifically related to a kind of truck cap rear suspension device.
Background technology
The truck that semi-floating Cab mounting or full-float cab suspend is housed, and its operator's compartment has better traveling comfort in the process of moving.Semi-floating Cab mounting or full-float cab suspend rear suspension device all are housed.The truck cap rear-suspending generally is divided into upper and lower two parts, and upper end is connected with operator's compartment, and lower end is connected with chassis frame.The Cab mounting upper and lower part is connected with shock absorber by spring, spring vertical or small angle inclination is usually arranged, in the Vehicle Driving Cycle process, because the road surface that truck left and right sides wheel travels is inconsistent, cause the vibration on chassis frame left side and right side inconsistent, thereby cause that operator's compartment rotates around Z axis when vehicle body system of axes X-axis is rotated, i.e. yaw vibration.Operator's compartment causes the lateral vibration of seat in operator's compartment around the rotation of Z axis, has reduced the traveling comfort of vehicle.Existing structure adopts stablizes pull bar or lateral damper absorption or restriction yaw vibration, and these two kinds of common complex structures of mode, take the space between the rear-suspending of left and right, affects the layout of other parts, particularly air filter.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of cab rear suspender, can either reduce the vibration of operator's compartment vertical direction, the left and right yaw of restriction operator's compartment, can also not take the space between the rear-suspending of left and right, improve space availability ratio.
For achieving the above object, the utility model provides a kind of cab rear suspender, comprises upper bracket, hydraulic lock, jounce bumper assembly, lateral damper, lower bracket.Described upper bracket is rotaryed connection with described hydraulic lock; Described hydraulic lock is fixedly connected with described jounce bumper assembly; Described jounce bumper assembly is rotaryed connection with described lower bracket; Described lateral damper one end is rotaryed connection by lining with described jounce bumper assembly, and the other end is rotaryed connection by lining with lower bracket.
Further, left back suspending is symmetrical arranged with right back suspending.
Further, described lateral damper lower end, lateral damper two ends are provided with lining, and lining is rubber bush or polyurethane lining.
Further, described jounce bumper assembly medi-spring is air bellow or coil spring.
Further, if adopt air bellow in described jounce bumper assembly, rear-suspending one or both sides relative set height-control valve, be used for controlling the length of air bellow.
Cab rear suspender provided by the utility model is simple in structure, and the parts reliable operation not only reduces vertical direction and the lateral vibration of operator's compartment, can also not take the space between the rear-suspending of left and right, improves space availability ratio.
The accompanying drawing explanation
Fig. 1 the utility model rear-suspending front view;
Fig. 2 the utility model rear-suspending left view;
Fig. 3 the utility model jounce bumper assembly structure schematic diagram;
Fig. 4 the utility model lateral damper structural representation.
The specific embodiment
Rear suspension device comprises upper bracket 1, hydraulic lock 2, lateral damper 3, jounce bumper assembly 5, lower bracket 6 as depicted in figs. 1 and 2, if adopt air spring vibration reduction device assembly, also should comprise levelling valve 4.Left back suspending is symmetrical arranged with the right back relative car load left and right longitudinal plane of symmetry that suspends.
Vehicle is when being subject to upwards impacting from road surface, and vehicle frame produces vertical direction thereupon and impacts, and is applied on operator's compartment by suspending, and the jounce bumper assembly energy absorption portion of rear-suspending is impacted, and reduces the vibration of operator's compartment; When vehicle, when being subject to the left-right asymmetry impact or turning to, operator's compartment produces the yaw vibration of relative vehicle frame, the lateral impact of lateral damper buffering, the yaw vibration of reduction operator's compartment.
Jounce bumper assembly lower end is provided with lining 7, by lining 7, with lower bracket, rotarys connection.Lateral damper 3 two ends are provided with lining 8, by lining 8, with jounce bumper assembly 5, with lower bracket 6, are connected respectively.Lining 8 can be rubber bush or polyurethane lining.
Jounce bumper assembly medi-spring can adopt coil spring or air bellow, if adopt air bellow, rear suspension device should suspend height-control valve is set in one or both sides.
