The invention discloses a back torsion beam suspension frame structure, which comprises a left longitudinal beam (4), a right longitudinal beam (4), a transverse beam (12), a lining casing (3), a vibration damper installation bracket (6) and a spring installation bracket (7), and is characterized in that: a transverse stabilizer rod (11) is arranged on a hollow part of the transverse beam (12), and is fixed on the left and right longitudinal beams (4) through left and right side brackets. A replaceable stabilizer rod is arranged on a back torsion beam suspension frame, so that the structures of components such as the transverse beam and the like are optimized, the total weight of the suspension frame is reduced, and the economic efficiency of an entire vehicle is realized. The back suspension frame is general, so that spare part cost of the same platform car type on the market is lowered, and better economic benefit is achieved. The entire stabilizer rod is hidden inside the transverse beam, so that the arrangement space of the back suspension frame is not influenced on the whole, the structure is simple and practical, and convenience is brought to implementation.
Description
Technical field
The invention belongs to automobile suspension system, in particular, the present invention relates to a kind of back torsion beam suspension structure.
Background technology
Suspension is the important component part of vehicle, is the connection load transfer device between vehicle body and the wheel, also is the important composition parts of vehicle safety, traveling comfort.The kind of suspension has a variety of, and suspension frame structure commonly used has twist beam type suspension, trailing arm type suspension, McPherson strut, wishbone suspension and many link-types suspension etc.Twist beam type suspension because have simple in structure, manufacturing cost is low relatively, have advantage such as good cost performance and adopted by a lot of vehicle.Be suspended in and satisfy on the intensity based, also will satisfy dynamic (dynamical) requirement.The roll rate of rear suspension is very big to handling stability influence, a lot of vehicles that adopt the back torsion beam suspension, and in order to satisfy the roll rate of rear suspension, thick and heavy beam design usually to promote roll rate.Even but the vehicle on the identical platform, because the variation of complete vehicle quality and car load centroid position, also different to the roll rate requirement of rear suspension, in order to satisfy the roll rate of suspension, the suspension of having to design again causes the commonality of suspension very poor.
Summary of the invention
Provide a kind of overall weight light and can satisfy the back torsion beam suspension of different automobile types roll rate requirement in order to address the above problem the present invention.
A kind of back torsion beam suspension structure; Comprise left longeron, right vertical beam, crossbeam, lining sleeve pipe, shock absorber mounting bracket and spring mounting bracket; At the crossbeam hollow bulb a horizontal stabilizer rod is installed, stabilizer rod is fixed on the left and right longeron through the support of left and right side.
Wherein, the support of left and right side all comprises before the stabilizer rod mounting bracket behind the mounting bracket and stabilizer rod, and mounting bracket is connected with left longeron, right vertical beam through freezing of landing edge place behind the preceding mounting bracket of stabilizer rod and the stabilizer rod.
Wherein, stabilizer rod is connected through mounting bracket before ball end and the stabilizer rod at preceding mounting bracket place; Mounting bracket place behind stabilizer rod, stabilizer rod passes stabilizer rod fixed hub assembly, and stabilizer rod fixed hub assembly is through bolt mounting bracket behind the stabilizer rod.
Further, stabilizer rod adopts hollow structure.
Further, the weight of stabilizer rod can be adjusted according to vehicle.
Further, lining sleeve pipe, shock absorber mounting bracket and spring mounting bracket all are connected with longeron through freezing of landing edge place.
Further, crossbeam is connected through freezing of lap-joint with left and right longeron.
Back of the present invention torsion beam suspension structure is when left and right longeron takes place to reverse relatively, and stabilizer rod can twist under the drive of longeron, thereby changes the roll rate of suspension.The roll rate of rear suspension is provided by stabilizer rod to a great extent, in suspension design, can the strength and stiffness of crossbeam be optimized, to reach the purpose that reduces weight.Different vehicles is different to the requirement of back torsion beam suspension roll rate, can realize through the stabilizer rod of changing different-stiffness.Stabilizer rod adopts hollow structure, reaches under the situation of equal torsional stiffness, and the stabilizer rod quality is lighter.
Advantage of the present invention is the stabilizer rod that can change through installation on the torsion beam suspension of back, and the structure of optimizing parts such as crossbeam alleviates the overall weight of suspension, realizes the economy of car load.Through changing the stabilizer rod of different-stiffness; Change the roll rate of back torsion beam suspension; Avoided because of roll rate does not meet the demands suspension not being designed again in the design of back torsion beam suspension in the new car exploitation, realized back torsion beam suspension general on different automobile types, reduced the die sinking expense of developing part again; Shorten the reliability test cycle of back torsion beam suspension, and then shortened the time-to-market of new car.Can be general because of rear suspension, reduced the vehicle listing spare part cost of identical platform vehicle later on, realize better economic benefit.Stabilizer rod integral body is hidden in crossbeam inside, does not influence the arrangement space of rear suspension on the whole, and is simple and practical, is convenient to realize.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
The overall schematic of torsion beam suspension structure behind Fig. 1 the present invention.Stabilizer rod assembly structure 2 is installed on the torsion beam suspension assembly of back through the fixed support of the left and right sides, and fixed point adopts bolted connection.Become symmetrical structure about suspension assembly.
Fig. 2 is a stabilizer rod installation place local structure scheme drawing.In conjunction with Fig. 1,2; Back of the present invention torsion beam suspension structure comprises: left longeron 4, right vertical beam 4 and the crossbeam that is connected the two 12; And lining sleeve pipe 3, shock absorber mounting bracket 6 and spring mounting bracket 7, also comprise before the stabilizer rod that is used for the stable installation bar mounting bracket 5 behind the mounting bracket 8 and stabilizer rod.Mounting bracket 5 all is connected with longeron 4 through freezing of landing edge place behind lining sleeve pipe 3, shock absorber mounting bracket 6, spring mounting bracket 7, the preceding mounting bracket 8 of stabilizer rod and the stabilizer rod, and crossbeam also is to be connected through freezing of lap-joint with longeron.Stabilizer rod 11 is connected through mounting bracket 8 before ball end 9 and the stabilizer rod at preceding mounting bracket 8 places.Mounting bracket 5 places behind stabilizer rod, stabilizer rod 11 passes stabilizer rod fixed hub assembly 10, and stabilizer rod fixed hub assembly 10 is through bolt mounting bracket 5 behind the stabilizer rod.
Stabilizer rod structural entity after the installation all is hidden in the hollow bulb of crossbeam, in the suspension hopping process, because of with crossbeam phenomenons such as identical movement tendency can not interfere being arranged.In order to realize the lightweight of vehicle, stabilizer rod can adopt hollow structure, when satisfying operating needs, reduces the overall weight of rear suspension.
