The balance shaft assembly in the heavy type automobile rear balanced suspension system comprises the whole type balance shaft and two balance shaft supports, wherein each balance shaft support is connected with one end of the whole type balance shaft in a transitional and matched mode through a central hole which is formed in each balance shaft support. The balance shaft assembly in the heavy type automobile rear balanced suspension system is characterized by further comprising a pull-down connection plate, connection through holes are formed at two ends of the pull-down connection plate, connection flange faces are arranged at the bottoms of the balance shaft supports, the pull-down connection plate is fixed on the connection flange faces of the balance shaft supports through the connection through holes, and therefore, bottoms of the two balance shaft supports are connected together through the pull-down connection plate.
Description
Technical field
The utility model relate to a kind of by balance shaft with and two ends on the balance shaft assembly that forms of balance shaft support, relate in particular to the balance shaft assembly in a kind of heavy motor vehicle back balance suspension system.
Background technology
Existing heavy motor vehicle for example adopts the back balance suspension system load-carrying capacity of integral type balance shaft strong, and is widely adopted in the engineering dump truck.Wherein the integral type balance shaft adopts the integrated shaft run through the frame width direction to forge to form, the middle part upwards arches upward to avoid to interfere with the transmission shaft occurrence positions, two ends adopt balance shaft support to support, the integral type balance shaft is assemblied in the hole of two balance shaft supports, and the formation transition fit connects, the parts such as balance shaft support is connected by midship mounting and vehicle frame, balance shaft two ends employing plain bearing and leaf spring are connected, and the leaf spring two ends straddle at middle back axle leaf spring slide plate and consist of balance suspension.Balance shaft assembly refers to the assembly parts that integral type balance shaft, balance shaft support, holding pin consist of, and the left and right balance shaft support lower end of existing balance shaft assembly is without union piece, and system rigidity is poor, causes that peripheral part wear out failure and endurance failure amount are large.
The utility model content
For deficiency of the prior art, the utility model aims to provide a kind of integral type balance shaft flexural deformation that reduces, and reduces its fracture failure and improves balance shaft assembly in the heavy motor vehicle back balance suspension system in its service life.
In order to address the above problem, balance shaft assembly in a kind of heavy motor vehicle back balance suspension system of the present utility model, comprise: integral type balance shaft and two balance shaft supports, each balance shaft support is connected with this integral type balance shaft one end transition fit by its centre hole; Balance shaft assembly in this heavy motor vehicle back balance suspension system is characterised in that: also comprise a drop-down connecting panel, the two ends of this drop-down connecting panel have connecting through hole; The bottom of described balance shaft support is provided with connecting flange faces; Drop-down connecting panel is fixed on the connecting flange faces of balance shaft support by its connecting through hole, so that link together by drop-down connecting panel between the bottom of two balance shaft supports.
Preferably, have three connecting through holes on each end of described drop-down connecting panel; Have two through holes and a tapped blind hole on the described connecting flange faces; Described drop-down connecting panel and connecting flange faces are bolted.
Preferably, the middle part width of described drop-down connecting panel is less than the width at these drop-down connecting panel both ends.
More preferably, be provided with the V-arrangement reinforced rib between the connecting flange faces of described balance shaft support and the centre hole, be provided with the bottom reinforced rib between the propelling rod bolt fastening hole on connecting flange faces and the balance shaft support.
The beneficial effects of the utility model are: drop-down connecting panel connects the balance shaft support bottom at balance shaft two ends, form a closed annular body, make balance shaft assembly become a closed ring, thereby raising system stiffness, so that balance shaft axle head angle of bend is reduced to 1/6 of former deflection, the balance shaft maximum stress reduces 30%, the fatigue failure number of times is increased to 45 times, greatly reduced critical parts in the integral type balance shaft assembly such as the damage amount of balance shaft and balance shaft support, reduced product after sale with maintenance cost.
