Abstract
The present invention relates to an automatic lift system for a pusher axle and/or a bridge axle of a truck. The automatic lift system raises the pusher axle and/or the bridge axle in the event of a tire blowout or low tire pressure to prevent the truck from swerving, spinning out or rolling over. The system includes a tire pressure sensor integrated to each of two wheels connected to the pusher axle and each of the two wheels connected to the bridge axle. Each tire pressure sensor is connected to a wired circuit and controller area network (CAN) of the truck for electronic communication with a control box. The control box receives tire pressure information from the sensors and transmits axle lift instructions in response to the tire pressure.
Claims20
A vehicle axle automatic lifting system comprising:
- a plurality of sensors integrated to the tires of a pusher axle;
- said plurality of sensors includes a first sensor and a second sensor;
- said first sensor monitors a first tire pressure of said pusher axle;
- said second sensor monitors a second tire pressure of said pusher axle;
- said first sensor and said second sensor report said first tire pressure and said second tire pressure to a controller;
- said controller compares said first tire pressure and said second tire pressure to a predetermined pressure;
- and
- said controller transmits an instruction signal to a lifting system electronic control unit of a pusher axle adjustment system to lift said pusher axle if said first tire pressure or said second tire pressure is less than said predetermined pressure.
A vehicle safety system comprising:
- a plurality of sensors integrated to the tires of a pusher axle;
- said plurality of sensors includes a first sensor and a second sensor;
- said first sensor monitors a first tire pressure of said pusher axle;
- said second sensor monitors a second tire pressure of said pusher axle;
- said first sensor and said second sensor report said first tire pressure and said second tire pressure to a controller;
- said controller compares said first tire pressure and said second tire pressure to a predetermined pressure;
- said controller transmits an instruction signal to a lifting system electronic control unit of a pusher axle adjustment system to lift said pusher axle if said first tire pressure or said second tire pressure is less than said predetermined pressure;
- said plurality of sensors includes a third sensor and a fourth sensor;
- said third sensor monitors a third tire pressure of a tag axle;
- said fourth sensor monitors a fourth tire pressure of said tag axle;
- said third sensor and said fourth sensor report said third tire pressure and said fourth tire pressure to said controller;
- said controller compares said third tire pressure and said fourth tire pressure to a predetermined pressure;
- and
- said controller transmits an instruction signal to a lifting system electronic control unit of a tag axle adjustment system to lift said tag axle if said third tire pressure or said fourth tire pressure is less than said predetermined pressure.
A method for automatically stabilizing a truck, the method comprising the steps of:
- integrating a plurality of sensors to the tires of a pusher axle wherein said plurality of sensors includes a first sensor and a second sensor;
- monitoring a first tire pressure of said pusher axle with said first sensor;
- monitoring a second tire pressure of said pusher axle with said second sensor;
- reporting said first tire pressure and said second tire pressure to a controller;
- comparing said first tire pressure and said second tire pressure to a predetermined pressure;
- and
- transmitting an instruction signal to a lifting system electronic control unit of a pusher axle adjustment system to lift said pusher axle if said first tire pressure or said second tire pressure is less than said predetermined pressure.
