Abstract
The utility model discloses a rear suspension for a mine dump truck with a protective cover, belonging to the technical field of vehicle suspension devices. The rear suspension comprises a lower seat lug, an upper seat lug, an aerating valve and an oil injection hole plug screw, wherein the oil injection hole plug screw is connected with the oil injection hole in the surface of the upper seat lug; and the aerating valve is connected with an aerating hole in the surface of the lower seat lug. The rear suspension also comprises an upper protective cover and a lower protective cover, wherein. The upper protective cover is used for shielding the oil injection hole plug screw; the lower protective cover is used for shielding the aerating valve; the upper protective cover is fixedly connected with the external wall of the upper seat lug and is arranged above the oil injection hole plug screw; and the lower protective cover is fixedly connected with the external wall of the lower seat lug and is arranged below the aerating valve. The rear suspension has the benefits of protecting the oil injection hole plug screw and the aerating valve by adding the protective cover, preventing hydraulic oil and nitrogen gas from leaking, prolonging the service life, and improving the performance.
Description
Technical field
The utility model hangs after relating to a kind of quarry tipper with protective case, belongs to the suspension device for vehicle technical field.
Background technology
Employed back suspension on the quarry tipper at present all be not with protective case, and the quarry tipper environment for use is very abominable; So extraneous stone and junk etc. are easy to oil-filled mouthful of plug screw or charge valve are damaged; And oil-filled mouth plug screw or charge valve then can cause hydraulic oil and nitrogen leakage in the suspension if damage, and greatly influence rear-mounted performance; Shorten rear-mounted service life, bring significant impact to vehicle '.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model hangs after a kind of quarry tipper with protective case is provided, and increases protective case pouring orifice plug screw and charge valve are protected.
To achieve these goals; The technical scheme that the utility model adopts is: hang behind a kind of quarry tipper with protective case, comprise a following ear, seat of honour ear, charge valve and pouring orifice plug screw, the pouring orifice plug screw is connected with the pouring orifice on seat of honour ear surface; Charge valve is connected with the inflation inlet on following ear surface; The following protective case of the last protective case that also comprises the pouring orifice plug screw that is used to screen and the charge valve that is used to screen, last protective case is fixedly connected on the ear outer wall of the seat of honour, is positioned at above the pouring orifice plug screw; Following protective case is fixedly connected on down on the seat ear outer wall, is positioned at the charge valve below.
Last protective case and seat of honour ear outer wall are bolted connection.
Following protective case is a bolted connection with following ear outer wall.
The beneficial effect of the utility model is: increase protective case pouring orifice plug screw and charge valve are protected, prevent the leakage of hydraulic oil and nitrogen, prolong the back and hang service life, improve rear-mounted performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, a following ear, 2, seat of honour ear, 3, go up protective case, 4, protective case down, 5, charge valve, 6, the pouring orifice plug screw.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 1, hang behind a kind of quarry tipper with protective case, comprise a following ear 1, seat of honour ear 2, charge valve 5 and pouring orifice plug screw 6; The pouring orifices on pouring orifice plug screw 6 and seat of honour ear 2 surfaces are connected, and charge valve 5 is connected with a following ear 1 surperficial inflation inlet, also comprise the last protective case 3 of the pouring orifice plug screw 6 that is used to screen and the following protective case 4 of the charge valve 5 that is used to screen; Last protective case 3 is fixedly connected on seat of honour ear 2 outer walls; Be positioned at pouring orifice plug screw 6 tops, following protective case 4 is fixedly connected on down on seat ear 1 outer wall, is positioned at charge valve 5 belows; Last protective case 3 is a bolted connection with seat of honour ear 2 outer walls, and following protective case 4 is a bolted connection with a following ear 1 outer wall.
Last protective case 3 is fixedly connected on seat of honour ear 2 outer walls, is positioned at pouring orifice plug screw 6 tops, and last protective case 3 can cover in pouring orifice plug screw 6; Prevent that pouring orifice plug screw 6 is directly exposed in the rugged environment, following protective case 4 is fixedly connected on down on seat ear 1 outer wall, is positioned at charge valve 5 belows; Following protective case 4 can cover in charge valve 5; Prevent that charge valve 5 is directly exposed in the rugged environment, protective case is protected pouring orifice plug screw and charge valve, prevents the leakage of hydraulic oil and nitrogen; Prolong the back and hang service life, improve rear-mounted performance.
