Power assembly suspension cushion integrating failure early warning function

Technical Field

The utility model relates to the technical field of automobile parts, in particular to a power assembly suspension cushion integrating a failure early warning function.

Background

The power assembly (engine, gearbox, etc.) suspension cushion is mainly used for connecting the power assembly and the frame on the vehicle, and can play a role in vibration isolation, so that the power assembly can run more stably and reliably.

The suspension cushion is generally made of rubber materials, and in the using process of a vehicle, rubber can lose efficacy under the influence of aging and vibration fatigue, so that the position of a power assembly is changed, and power output and safe operation of the vehicle can be seriously influenced, so that the monitoring of the operation state of the suspension cushion is particularly important, but the installation position of the suspension cushion on the vehicle is generally arranged at the positions which are difficult to visually inspect, such as the lower parts of a vehicle body and a vehicle frame, the lower part of an engine compartment and the like, and the difficulty of finding failure hidden troubles by inspection is further increased due to the coverage of oil sludge and the like on the surface of the suspension cushion in the operation process of the vehicle.

Above can be seen, current suspension cushion receives restriction such as mounted position, and at vehicle operation in-process, be difficult to confirm the state of cushion through the mode of visual inspection, the user can't discover the risk that the suspension cushion became invalid in advance, can only lose efficacy at the cushion and just can discover and change it after producing the influence to vehicle operation, can reduce the ageing of vehicle availability factor and transportation goods to influence vehicle operation safety.

Disclosure of Invention

The utility model aims to provide a power assembly suspension cushion integrating a failure early warning function, which solves the problems of shaking, potential safety hazards and easiness in collision and scratching of left and right longitudinal beams in a lifting process, enables the whole lifting process to be safer and simpler, improves the production efficiency of a frame riveting line, and simultaneously ensures the product quality.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a power assembly suspension cushion of integrated failure early warning function which characterized in that includes:

the system comprises a suspension cushion, a vehicle control unit VCU and a warning device;

the suspension cushion comprises a vibration isolation rubber body, an upper framework and a lower framework clamp, wherein the upper framework and the lower framework clamp are clamped on the upper side and the lower side of the vibration isolation rubber body;

the electrode bottom plate and the failure signal generator contact are electrically connected with a VCU (vehicle control unit) through a wire harness and a wire harness plug connector respectively;

and the VCU of the vehicle control unit controls and connects with the warning device.

The upper framework of the suspension cushion is connected with the end fixing support of the power assembly, and the lower framework is connected with the end fixing support of the frame.

The warning device is arranged on the cab instrument.

The power assembly suspension cushion integrating the failure early warning function can well solve the problem that the cushion failure hidden danger cannot be checked visually in the prior art, and the electric control system is combined with the physical structure of the suspension cushion, so that before the suspension cushion fails, the electric control system outputs signals, the instrument device lights signal lamps or gives out alarm sound and the like to remind a user of performing cushion maintenance and replacement in advance, and the risks of whole vehicle failure and the like caused by the failure of the suspension cushion are effectively reduced. For vehicles (such as fire engines and fresh-living goods transport vehicles) which have high requirements on the reliability of the whole vehicle and high transportation timeliness, vehicles (such as mining vehicles and the like) which have relatively bad operation working conditions of a power assembly and run continuously are integrated with the suspended cushion, after the suspended cushion has the failure early warning function, the labor intensity of manual inspection of a user on the suspended cushion of the vehicle can be effectively reduced, and the operation convenience of daily maintenance of the vehicle is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

The power assembly suspension cushion integrating the failure early warning function comprises a vibration isolation rubber body 2, wherein the lower side of the vibration isolation rubber body 2 is connected with a frame end fixing support 7 through a lower framework 1, and the upper side of the vibration isolation rubber body 2 is connected with a power assembly end fixing support 9 through an upper framework 3. An electrode bottom plate 5 is embedded in the vibration isolation rubber body 2, a failure signal generator contact 4 is embedded above the electrode bottom plate 5 at a preset height distance, the failure signal generator contact 4 and the electrode bottom plate 5 are respectively connected and communicated with a vehicle control unit VCU 10 through a wire harness and a wire harness connector clip 6, when the vibration isolation rubber body 2 reaches a preset compression amount, the failure signal generator contact 4 is contacted with the electrode bottom plate 5 below to form a closed circuit, the electric signal is sent to the vehicle control unit VCU 10 through the wire harness, the vehicle control unit VCU 10 sends an instruction to a warning device 11 controlled to be communicated with the warning device after processing the received electric signal, and the warning device 11 reminds a user by lighting an indicator lamp or alarming sound.

The operation method of the frame longitudinal beam hoisting tool comprises the following steps:

the working principle is as follows: when the suspension cushion is determined to be completely invalid through calculation, the rubber compression amount when the upper framework and the lower framework are in rigid contact is set, according to the value, the space distance between the contact of the failure signal generator 4 and the electrode bottom plate of the failure signal generator 5 is set, before the cushion reaches the failure compression amount, the contact is firstly contacted with the electrode bottom plate to form a closed circuit, the closed circuit outputs an electric signal to a VCU (vehicle control unit) of a vehicle controller 10, the VCU outputs an electric signal to an instrument device in a cab after receiving the signal, and the instrument device reminds a user to maintain or replace the cushion in modes of lighting an indicator lamp or sending alarm sound and the like.

After the suspended cushion integrates the failure early warning function, a user can arrange to replace and maintain the suspended cushion according to the reminding before the suspended cushion fails and affects the normal operation of the whole vehicle. The safe operation of the vehicle is prevented from being influenced due to the sudden failure of the suspension cushion, the vehicle parking fault is avoided, and extra transportation loss is avoided for users.

In summary, although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the utility model.
