Abstract
The utility model discloses a hinged type engineering vehicle of a connecting rod type suspension mechanism, which comprises a vehicle frame, a transverse beam arranged on the vehicle frame and a vehicle bridge located on the lower portion of the vehicle frame. A supporting base is respectively arranged on two sides and the middle portion of the transverse beam and connected with a lower connecting rod and an upper connecting rod which are symmetrical longitudinally, the lower connecting rod and the upper connecting rod are respectively hinged to two sides and the upper portion of the vehicle bridge, the vehicle bridge is connected with the transverse beam through vibration reduction springs arranged symmetrically, and two sides of the vehicle bridge are connected with transverse connecting rods. The vehicle frame and the vehicle bridge are connected via the connecting rod type suspension mechanism which bears vehicle running driving force, brake force and the like, and three longitudinal rods keep far away from a transmission mechanism, thereby leading the connecting rod mechanism to be disposed conveniently and flexibly, and effectively improving running property of the whole vehicle.
Description
Technical field
The utility model relates to a kind of engineering truck, is the rear-mounted articulated con-rod of a kind of engineering truck mechanism specifically, can improve the stability that car load travels.
Background technology
At present, along with the continuous construction of domestic nonferrous metal mine and water project, the radial type engineering truck is more and more used with its alerting ability on walking mode.Radial type engineering truck hitch wherein plays key role to the riding stability of this vehicle.But most radial type engineering truck hitches mainly adopt the trigonometric expression equalizer bar to connect vehicle frame and vehicle jackshaft, back axle, and the trigonometric expression equalizer bar is installed in the vehicle frame bottom, and its rear end connects vehicle bridge.Because the vehicle bridge front portion is furnished with transmission device, this trigonometric expression balance posture hitch must be dodged the parts of transmission device, and this problem of bringing of dodging is that the stability that car load travels is produced certain influence.Therefore, providing a kind of desirable hitch mode is to need at present to solve and perfect content.
Summary of the invention
In view of above-mentioned present situation, the purpose of this utility model provides the rear-mounted articulated con-rod of a kind of engineering truck mechanism, by selecting the link-type hitch for use, efficiently solves the influence of hitch to the car load rideability.
The technical solution that realizes above-mentioned purpose is: the rear-mounted articulated con-rod of engineering truck mechanism, comprise vehicle frame and the crossbeam of installing on it, and be positioned at the vehicle bridge that the vehicle frame bottom is provided with; Wherein, be connected with lower link and boxed rod of vertical symmetry on the bearing that is provided with respectively at described crossbeam both sides and middle part, respectively with being hinged of vehicle bridge both sides and top; Described vehicle bridge is connected with crossbeam by symmetrically arranged damping spring; The vehicle bridge both sides are connected with horizontal connecting rod.Like this, by flexibly connecting to link-type hitch and vehicle bridge, vehicle frame in length and breadth, when vehicle ' met bump, the formula hitch by this link-type was installed in the vehicle frame bottom, and the swing of hitch adapts to the road surface.
According to scheme of the present utility model, the described rubber shaft bearing that is provided with to connecting rod and vehicle bridge, vehicle frame end in length and breadth is connected.
In above-mentioned, related damping spring is to select the rubber damping spring for use, is born by the rubber damping spring between vehicle bridge and the vehicle frame in order to the load that control hitch bonded assembly vehicle bridge is born.
In this was novel, the connecting rod of related link-type hitch was connected to movable the installation with vehicle bridge, vehicle frame and is connected.When adapting to protruding road surface, the swing by this link-type hitch adapts to the road surface.
In sum, the rear-mounted articulated con-rod of a kind of engineering truck mechanism that the utility model provides, adopted the link-type hitch to connect vehicle frame and vehicle bridge, swing by this link-type hitch makes vehicle adapt to the road surface, and bear the propulsive effort of vehicle ' and braking force etc., three longitudinal ties make that away from transmission device the connecting rod mechanism arrangement convenience is flexible, have effectively improved the rideability of car load.
Description of drawings
Fig. 1 is this later-model structural representation.
The specific embodiment
The utility model embodiment in conjunction with the accompanying drawings is described in further detail.
By a kind of radial type engineering truck that adopts connecting rod mechanism that hangs shown in Figure 1, comprise the vehicle frame 5 of symmetry and go up the crossbeam 7 that is provided with, be arranged on the crossbeam 7 in vehicle frame 5 outsides symmetry rubber damping spring (figure does not mark) is installed; This rubber damping both ends of the spring connects vehicle bridge 2; Vertical symmetrically arranged lower link 1 of 2 liang of terminations of described vehicle bridge, the other end that makes its lower link 1 are provided with bearing on the vehicle frame 5 inboard crossbeams 7 and are hinged with being positioned at; A hinged boxed rod that vertically is provided with 6 is formed a link-type hitch between bearing that has at crossbeam 7 middle parts and vehicle bridge 2 upper ends.Then the pedestal two ends that have in vehicle bridge 2 both sides are provided with rubber arthrosis bearing 4, and this rubber arthrosis bearing 4 is connected with the tranverse connecting rod of laterally installing 3.Therefore, each the connecting rod two ends in the hitch all adopt the rubber arthrosis bearing to be connected with vehicle bridge 2, vehicle frame 5, can be around the swing of rubber arthrosis bearing 4 places of end.Equally, vehicle bridge 2 is connected by the rubber damping spring with vehicle frame 5, and vehicle bridge 2 relative vehicle frames 5 can up-and-down movements and swung, and adapts to vehicle at rugged road traveling.
In the utility model, each connecting rod of related link-type hitch is connected to movable the installation with vehicle bridge, vehicle frame and is connected.
In above-mentioned, vehicle frame is vertically arranged three connecting rods, connecting rod of vehicle frame lateral arrangement.
