Abstract
A self-adaptive balanced suspension device improves integrated force conditions of through shafts of balanced suspensions and balancing shaft brackets when entire vehicles are over loading and through shafts and balancing shaft brackets of balanced suspensions bear twist force of vehicle frames. The self-adaptive balanced suspension device comprises a left balancing shaft bracket, a right balancing shaft bracket, a tile shape gland bush of a through shaft of the balanced suspension, a balanced suspension shaft, a balancing shaft bossing, a through shaft of the balanced suspension, limited brackets and a thrust rod connecting bracket. The utility model is characterized in that the through shaft of the balanced suspension is an integral hollow pipe fitting, a part of the through shaft of the balanced suspension which is between the left balancing shaft bracket and the right balancing shaft bracket is a bend structure, the through shaft of the balanced suspension is impacted by the tile shape gland bush and is fixed in a circular hole which is formed by the tile shape gland bush and a groove arranged on the lower ends of the left balancing shaft bracket and the right balancing shaft bracket, two limited brackets are respectively clung to the outer end face of the groove arranged on the left balancing shaft bracket and the right balancing shaft bracket and are fixed on the through shaft of the balanced suspension via a thrust rod bolt, and the thrust rod connecting bracket is fixed on the outer side of the limited bracket.
Description
Technical field
The utility model relates to the commercial car equalizing-suspension device.
Background technology
The various balance suspension products that existing heavy type commercial automobile uses, in the overload transportation, when perhaps under abominable road conditions condition, travelling, the reason of the aspects such as the huge inertial impact force that forms and vehicle frame self distortion of jolting because of vehicle, cause balance suspension axle thru shaft twisted off near balance shaft support place, the balance shaft support ftractures or from parts frequent breakage such as the bolt hole fractures that connects to ground from the balance shaft positioning bolt hole.Early stage is at the terms of settlement of balance suspension product bug, mainly be to set about: balance suspension thru shaft axle is adopted to forge the part blank and do add bulk processing or adopt whole steel pipe type thru shaft from the following aspects, the balance shaft support will be except that will thickening with the base plate of vehicle frame binding face, gusset has also been done respectively to strengthen handling everywhere, the transition R radian at each faying face place is suitably strengthened, but all can fundamentally not eliminate the reason that the balance suspension product frequently breaks down.
Summary of the invention
The utility model proposes a kind of balance suspension thru shaft, balance shaft support bear comprehensive force-bearing situation such as vehicle frame distortion power under the car load fully loaded transportation condition self-adapting type equalizing-suspension device that improves.
The utility model self-adapting type equalizing-suspension device, prop up and be configured to by left and right balance shaft support, balance suspension perforation bearing shell shape gland, balance suspension axle, equalizer bearing hub, balance suspension thru shaft, limiting bracket, propelling rod connection, it is characterized in that: the balance suspension thru shaft is for being whole hollow pipe fitting, and the position of balance suspension thru shaft between left and right balance shaft support is bend pipe structure; The balance suspension thru shaft directly is pressed abd fixed in the groove of left and right balance shaft support lower end and the circular hole that watt shape gland forms by watt shape gland; Two limiting brackets are close to respectively on the outer face at left and right balance shaft rack groove place, and are bolted on the balance suspension thru shaft by propelling rod, and propelling rod connects support and is fixed on the limiting bracket outside.
To further improvement in the technical proposal: the maintenance alarm switch is equipped with in the groove side that the balance suspension thru shaft is installed at left and right balance shaft support, and the position of mounting hole deflection certain angle of corresponding maintenance alarm switch runs through and is drilled with maintenance alarm switch open hole on the balance suspension thru shaft.
The utility model self-adapting type equalizing-suspension device, the balance suspension thru shaft directly is pressed abd fixed on a left side by a watt shape gland, in the circular hole that the groove of right balance shaft support lower end and watt shape gland form, under stressed excessive situation, the balance suspension thru shaft can be with respect to a left side, right balance shaft support produces relative rotation, changed the balance suspension thru shaft on the whole, the force-bearing situation of balance shaft support: during the car load overload, the balance shaft support that is installed on vehicle frame two longerons can reverse to adapt to the variation of vehicle frame lower aerofoil along with vehicle frame twists the amplitude trace, when car load is traveling in rugged road surface, the left and right sides, elastic deformation takes place the balance suspension thru shaft automatically changes to adapt to left and right sides balance shaft support high and low position, strengthen balance suspension thru shaft and the antitorque commentaries on classics of balance bracing strut, fatigue performance, thereby avoid to greatest extent balance suspension axle thru shaft twisted off near balance shaft support place with the balance bracing strut from balance suspension thru shaft positioning bolt hole cracking or from the generation of phenomenons such as the bolt hole fracture that connects to ground, prolong the service life of equalizing-suspension device, reached the purpose of saving social resources and increasing economic benefit for the car load user.When being provided with the maintenance alarm switch, when the maintenance alarm switch open hole of balance suspension thru shaft reverses maintenance alarm switch place to the balance shaft support, switch contact open in usual is stretched out or is cut off by rotating balance suspension thru shaft, remind the annunciator that is installed on the facia board after the maintenance circuit closure promptly to begin continuous firing, remind chaufeur maintenance equalizing-suspension device till fault is eliminated.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model self-adapting type equalizing-suspension device.
Fig. 2 is the construction profile scheme drawing of the utility model self-adapting type equalizing-suspension device.
The specific embodiment
Self-adapting type equalizing-suspension device is as shown in Figure 1, 2 connected support 7 and is constituted by left and right balance shaft support 3, balance suspension perforation bearing shell shape gland 5, balance suspension axle 2, equalizer bearing hub 1, balance suspension thru shaft 4, limiting bracket 6, propelling rod.Balance suspension thru shaft 4 is for being whole hollow pipe fitting, and the position of balance suspension thru shaft 4 between left and right balance shaft support 3 is bend pipe structure; Balance suspension thru shaft 4 directly is pressed abd fixed in the circular hole of the groove of left and right balance shaft support 3 lower ends and 5 formation of watt shape gland by watt shape gland 5; Two limiting brackets 6 are close to respectively on the outer face of left and right balance shaft support 3 grooves, and are fixed on the balance suspension thru shaft 4 by propelling rod bolt 11, and propelling rod connects support 7 and is fixed on the limiting bracket outside.In the groove side that left and right balance shaft support 3 is installed balance suspension thru shafts 4 maintenance alarm switch 8 is housed, the position of mounting hole deflection certain angle of corresponding maintenance alarm switch runs through and is drilled with maintenance alarm switch open hole 9 on the balance suspension thru shaft.As shown in Figure 2, distance rod assembly 10 also is connected support 7 connections by propelling rod bolt 11 with limiting bracket 6 and propelling rod.
