Abstract
The invention discloses a lifting device for an automobile spare tire. The lifting device comprises an upper swing arm, a lower swing arm and a spare tire fixing frame, wherein the upper ends and the lower ends of the upper swing arm and the lower swing arm are respectively connected with a frame and the spare tire fixing frame; the upper swing arm, the lower swing arm, the frame and the spare tire fixing frame are connected to form a parallelogram mechanism; the edge of the parallelogram mechanism, which is positioned on the frame, is vertical; and a driving mechanism for driving the upper swing arm or the lower swing arm to rotate around a hinge point of the upper swing arm or the lower swing arm is arranged on the frame. According to the lifting device disclosed by the invention, the edge of the parallelogram mechanism, which is positioned on the frame, is vertical, so that a spare tire fixing bracket is always vertically lifted; and the spare tire is vertically fixed on the spare tire fixing bracket, so that the spare tire is longitudinally arranged and further the spare tire is always kept in a vertical state during the lifting, the lifting space is saved and the mounting on the automobile is facilitated. In addition, the spare tire falling on the ground is enabled to erect and the mounting is facilitated.
Description
Technical field
The present invention relates to a kind of automobile spare tire lifting gear.
Background technology
Along with the develop rapidly of automatic technology, convenient, fast, and save time, the labour-saving automobile spare tire lifting gear more and more is applied on the autotruck.Yet present most of automobile spare tire lifting gears all adopt spare tyre laterally to place, and have limited like this arrangement.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of automobile spare tire lifting gear that spare tyre is vertically arranged of being convenient to is provided.
In order to solve the problems of the technologies described above, the present invention includes top link, lower swing arm and tire carrier frame, top link is connected up and down, and two ends are connected with tire carrier frame with vehicle frame respectively with lower swing arm, top link, lower swing arm, vehicle frame and tire carrier frame connect into a parallel-crank mechanism, the limit that is positioned in the parallel-crank mechanism on the vehicle frame is vertical, and vehicle frame is provided with and drives the driver train that top link or lower swing arm rotate around its hinge-point on vehicle frame.
Described driver train comprises oil pump and oil cylinder, the permanent seat that top link is connected with lower swing arm by separately is connected with vehicle frame, top link and lower swing arm and permanent seat are hinged, permanent seat is fixed on the vehicle frame, one end of oil cylinder is connected with top link, the other end of oil cylinder is connected with the permanent seat of top link, and oil cylinder connects oil pump, and oil pump is arranged on the vehicle frame.
For the ease of arranging at two front axle automobiles, described top link and lower swing arm include two bodies of rod, and the two ends fork is drawn close in the centre of two bodies of rod.
The invention has the beneficial effects as follows: the present invention is by forming parallel-crank mechanism to provide elevating function to spare tyre between upper and lower swing arm and spare tyre fixed support and the vehicle frame, because the limit that is positioned on the vehicle frame in the parallel-crank mechanism is vertical, therefore the spare tyre fixed support is vertical lifting always, spare tyre vertically is being fixed on the spare tyre fixed support, so that spare tyre is vertically arranged, therefore can make spare tyre in lifting process, remain vertical state, save the lifting space, be convenient to install onboard, and can guarantee that the spare tyre that falls earthward erects, be convenient to install.

Fig. 2 is the structural representation of initial condition of the present invention;
Fig. 3 is the structural representation of final condition of the present invention;
Fig. 4 is part 4 among Fig. 1,5 and 6 structural representation enlarged drawing;
Among the figure: 1, oil pump, 2, load lifting cylinder, 3, permanent seat; 4, top link, 5, lower swing arm, 6, the spare tyre fixed support, 7, spare tyre.
The specific embodiment
Such as Fig. 1-a kind of specific embodiment shown in Figure 2, it comprises oil pump 1, load lifting cylinder 2 and jacking system, described jacking system comprises top link 4, lower swing arm 5 and spare tyre fixed support 6, top link 4 is connected an end and respectively is connected with vehicle frame by a permanent seat 3 with lower swing arm, top link 4 and lower swing arm 5 are hinged with permanent seat 3, permanent seat 3 is fixed on the vehicle frame, and the other end and the spare tyre fixed support 6 of top link 4 and lower swing arm 5 are articulated and connected; Load lifting cylinder 2 is articulated and connected between the permanent seat of top link 4 and top link 4; As shown in Figure 4, top link 4 and lower swing arm 5 parallel and equal in length, top link 4, lower swing arm 5, vehicle frame and spare tyre fixed support 6 formation double-crank mechanisms are parallel-crank mechanism like this.The limit that is positioned in the parallel-crank mechanism on the vehicle frame is vertical.
Principle of work:
Spare tyre 7 is fixed on the spare tyre fixed support 6, and it is the parallel-crank mechanism movement characteristic that the present invention fully uses double-crank mechanism: two cranks are made rotating in same direction with identical cireular frequency, and connecting rod is done translation.Make spare tyre 7 all the time with vertically vertical state, finish dipping and heaving.
The initial condition of this device as shown in Figure 2, parallel-crank mechanism is in collapsed state.
When needs are changed spare tyre, under oil pump 1 and load lifting cylinder 2 promotions, the double crank of parallel-crank mechanism is that upper and lower swing arm rotates with constant angular velocity simultaneously in the same way, promotes immediately spare tyre holder and does translation, make spare tyre 7 remain vertical state until spare tyre 7 is fallen the bottom surface, as shown in Figure 3.When spare tyre 7 was packed up, lifting mechanism was with the equal state counter motion, until spare tyre 7 packs up, as shown in Figure 2.
