Detailed description of the invention
Referring to Fig. 1, it is the structural representation of one embodiment of the invention passenger vehicle motor bus leaf spring double wish-bone arm type independent rear suspension. As shown in the figure: it is taken turns 11, two height adjusting valves of 10, two vibroshock upper brackets of 9, main reducing gear of 8, six connecting cross beams of 7, two gripper shoes of limit support, 13, four leaf spring connecting devices of 12, two amortisseurs 14, eight bracer 16, two brakes 17 of 15, eight ball pivots by 3, two leaf spring Top Crossbeams of 2, two supporting plates of 1, two semiaxis of two leaf spring lower cross arms, 5, two U-bolts of 4, two bolt brackets 6, two and four flexible members 18 are constituted. Wherein: described two leaf spring lower cross arms 1 and two leaf spring Top Crossbeams 4 are arranged in subframe both sides, leaf spring lower cross arm 1 and leaf spring Top Crossbeam 4 one end are connected leaf spring connecting device 14, leaf spring lower cross arm 1 and leaf spring Top Crossbeam 4 other end and are connected with wheel limit support 7 by pivot pin; Described subframe is to be made up of two gripper shoes 8 and six connecting cross beam 9 welding, two gripper shoes 8 lay respectively at the both sides of main reducing gear 10, three connecting cross beams 9 are positioned at above main reducing gear 10, the other three connecting cross beam 9 is positioned at below main reducing gear 10, and six connecting cross beams 9 are between two gripper shoes 8; Two described wheel limit supports 7 are positioned at the both sides of suspension, and wheel limit support 7 is connected with brakes 17; Leaf spring connecting device 14 is connected by ball pivot 16 with a bracer 15; A described bracer 15 is bolted with gripper shoe 8; The lower end of described flexible member 18 is connected with supporting plate 3, and upper end is connected with vehicle frame; Two described supporting plates 3 are positioned at the both sides of subframe, and supporting plate 3 is connected with wheel support 7 top, limit by bolt bracket 5, U-bolt 6; The lower end of described vibroshock 13 is connected with wheel limit support 7, and upper end is connected with vibroshock upper bracket 11, and two described vibroshock upper brackets 11 are respectively welded in two gripper shoes 8; Two described semiaxis 2 are arranged in main reducing gear 10 both sides, and semiaxis 2 one end is connected with main reducing gear 10 by universal joint, and the other end is connected with wheel limit support 7 by universal joint; Four described flexible members 18, the every side of subframe is respectively arranged with two flexible members 18, and two flexible members 18 of every side are arranged on the both sides of supporting plate 3; Subframe both sides are respectively provided with a height adjusting valve 12, are positioned at the side of vibroshock upper bracket 11, are arranged in two gripper shoes 8 by bolt. Described flexible member 18 is combined air air spring. Described leaf spring lower cross arm 1 and leaf spring Top Crossbeam 4 are used as upper and lower transverse arm by processing leaf spring. Described supporting plate 3 is processed by leaf spring.
In the present invention, four flexible member 18(such as air spring) upper end be fixed on bus body (vehicle frame), lower end is arranged on supporting plate 3, and four flexible members 18 subject deadweight and the load of passenger vehicle latter half; Two height adjusting valves 12 are arranged on the side of two amortisseurs 13, when bus body is impacted and pitches, can pass through height adjusting valve 12 and regulate the pressure in flexible member 18, thus regulating the air bag spring rate as air spring effect. Two amortisseurs 13 are separately mounted to the both sides of subframe, top is fixed with amortisseur upper bracket 11 by bolt, lower end by being hingedly fixed on wheel limit support 7, when bus body is impacted and is pitched can the energy of absorption portion, reduce the amplitude that passenger vehicle is overturned up and down. 1, two leaf spring Top Crossbeams 4 of two leaf spring lower cross arms are also arranged in the both sides of subframe, for transmitting the side force of passenger vehicle, keeping the lateral stability 6 of passenger vehicle. As a kind of optimal way, described leaf spring lower cross arm 1 and the length of leaf spring lower cross arm 4 are 310mm or more than 310mm, and reason is: due to the extended length of upper lower cross arm, decrease the wheelspan change of passenger vehicle rear suspension, reduce the abrasion of tire.
In the present invention, the supporting plate of the flexible member of independent suspension is bending leaf spring, reduces the setting height(from bottom) of vertical direction, such that it is able to reduce floor level, it is possible to so that suspension can easily be arranged on vehicle frame. Top Crossbeam and lower cross arm in the present invention take plate spring structure, replace original casting structure, greatly reduce the gross mass of rear suspension, reduce brake force, improve braking ability. In a word, use present configuration, reduce the abrasion of tire, reduce the setting height(from bottom) of vertical direction flexible member, reduce the gross mass of rear suspension, improve braking ability, such that it is able to reduction floor level, it is possible to so that suspension can easily be arranged on vehicle frame. Certainly, this structure is also applied for other automobile needing to install the independent rear suspension of double wish-bone arm type.
It is only presently preferred embodiments of the present invention in sum, is not used for limiting the practical range of the present invention. Namely all equivalences made according to the content of the present patent application the scope of the claims change and modify, and all should be the technology category of the present invention.
