Abstract
The disconnected type balance suspension for the chassis of the automobile crane comprises a thrust rod assembly, balance supports, plate springs and plate spring seats and is characterized in that the number of the plate springs is four, the balance supports are two independent balance supports which are welded with two sides of a chassis frame of the crane into a whole respectively, and a communication shaft which is connected with the two balance supports in the prior art is omitted. The utility model discloses can effectively alleviate the dead weight of balanced suspension, reduce chassis focus height, satisfy under the mobile crane operation requirement condition, improve the trafficability characteristic of whole car and the stability that whole car went.
Description
Technical field
The utility model relates to special-use vehicle, relates in particular to a kind of Crane Truck Chassis breakaway-element balance suspension, is used for car hosit chassis special suspension system.
Background technology
When Crane Truck Chassis is when using the General Motors equalizing suspension system, because the Crane Truck Chassis square chest is welding part structure, panel height generally surpasses 470mm, adopt the General Motors balance suspension that chassis height is increased about 200mm, because the car load height can not surpass 4 meters, this just adds to the difficulties to the installation of last dress.Effectively reduce car hosit chassis special height, last installing meter and raising car load crossing ability are benefited.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind ofly can effectively reduce chassis height, the Crane Truck Chassis breakaway-element balance suspension of the crossing ability of raising car load.
For achieving the above object, the utility model adopts following technical scheme: a kind of Crane Truck Chassis breakaway-element balance suspension, comprise distance rod assembly, balance bracket, leaf spring and spring block, it is characterized in that described plate spring sheet number is four, described balance bracket is two balance brackets that are welded as a whole with hoisting crane chassis frame both sides independently and respectively, the existing connection shaft that connects two balance brackets of cancellation.
In such scheme, be connected with a locating dowel pin parallel between described spring block and the balance bracket with wheel hub, be provided with the locating piece that prevents the locating dowel pin end float misalignment at the locating dowel pin two ends, leaf spring is installed on the spring block, and spring block and leaf spring can rotate up and down in balance bracket around locating dowel pin.
In such scheme, described leaf spring can be fixed on the spring block with U-bolt.
The utility model especially adopts and makes the plate spring sheet number into four by seven owing to adopt technique scheme; The existing connection shaft that connects two balance brackets of cancellation; Make balance bracket into the integrally welded structure of vehicle frame feature by assembly part, therefore, can effectively alleviate the deadweight of balance suspension, reduce the chassis height of gravitational center, satisfying under the car hosit operating needs condition, improving the crossing ability of car load and the stability that car load travels.
Description of drawings
Fig. 1 is the utility model embodiment front view.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Referring to Fig. 1, Fig. 2, present embodiment is mainly by distance rod assembly 1,2,7,9, balance bracket 4, locating dowel pin 5, locating piece 6, leaf spring 8, compositions such as spring block 11 and U-bolt 10.8 numbers of described leaf spring are four, and described balance bracket 4 is two balance brackets that are welded as a whole with hoisting crane chassis frame 3 both sides independently and respectively, the existing connection shaft that connects two balance brackets of cancellation.Spring block 11 usefulness locating dowel pins 5 are connected on the balance bracket 4, and pin locating dowel pin 5 with locating piece 6, prevent locating dowel pin left and right sides play; Leaf spring 8 usefulness U-bolts 10 are fixed on the spring block 11, and spring block 11 and leaf spring 8 assembly parts can rotate up and down in balance bracket 4 around locating dowel pin 5, to realize the function of balance suspension.
Because the hoisting crane chassis frame is the square chest structure, vehicle frame is antitorque and anti-bending strength is good, and the connection shaft of the general suspension of car chassis can be cancelled, so improved the crossing ability on chassis balance suspension weight saving described in the utility model the time.
Claims (3)
